- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string  

is the method for you. You can use it as :

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    //Your code

    if([textField.text isEqualToString:@"xyz"])
    {
        textField.text = @"Text you want to set";
    }
}  

This method is called when you type any character on keypad.
